Metafemur apex penultimate set of macrosetae with 2 setae, antepenultimate set of macrosetae with 1 seta, without extra macrosetae proximal of typical 2+2+1. Metatibia proximal seta of PD distad of proximal seta of AD or equidistant from tibia base, row AD intercalary setae simple or row AD intercalary setae cucullate, without basal stout setae on dorsal surface, row PD macrosetae subequal in length to AD macrosetae, row PD macrosetae alternating short and long or row PD macrosetae more or less equal in length, basal dorsal width much wider than width near apex, pecten with setae subequal in length. Metatarsomere I expanded apically, short, stout, plantar setae all simple. Metatarsomere I pecten: number of platellae 6-7 . Metatarsomere I pecten inner apical seta platelliform.
Male Genitalia. Valve articulated with pygofer and subgenital plates, with short point of articulation with pygofer. Pygofer dorsoapical margin incised to near mid-length, macrosetae well differentiated into several rows, without dense tufts of thick or fine setae, without ventral tooth, spine, or process or with ventral tooth, spine, or process, without dorsal tooth, spine, or process, posterior margin without teeth or serrations. Segment X sclerotized laterally and dorsally, not particularly long or broad. Subgenital plates triangular, longer than width, outer margin convex, apex pointed, macrosetae scattered, irregularly arranged or with two lateral rows of macrosetae, or with some irregularly arranged macrosetae near lateral margin, without or with few long fine setae or with some medium to long fine setae laterally or dorsally. Style preapical lobe short, rounded or pointed or preapical lobe prominent; lobate, digitate, or pointed, apophysis shorter than rest of style, apophysis straight, apophysis apex rounded, apophysis inner (posterior) margin without teeth, apophysis irregularly denticulate. Aedeagus without processes arising from base, without medial processes, with one pair of apical processes, depressed, flagellum arising from ventral part of socle, symmetrical or asymmetrical, moderate to long, gonoduct not sclerotized basad of aedeagal base, gonopore subapical, on ventral side, with a single shaft and gonopore, preatrium absent or very short. Phragma membranous. Connective anterior arms somewhat divergent, (Y- or U-shaped), stem present, shorter than anterior arms, without processes.
Female Genitalia. Pygofer with numerous macrosetae. Ovipositor not protruding far beyond pygofer apex.
